PROBLEM TO BE SOLVED: To provide an inflator which achieves improvement of productivity and reduction of manufacturing costs while improving the combustion gas discharge capacity.SOLUTION: An inflator of an air bag device includes: an inner cylindrical member 104 provided in a cylindrical housing; a granular gas generating agent filling the inner cylindrical member 104; and a coil spring 121 having an outer periphery along an inner peripheral surface of the inner cylindrical member 104. A gas circulation hole 104d for discharging a generated gas is formed on a cylindrical wall of the inner cylindrical member 104. A pitch of the coil spring 121 is set so as to be smaller than a diameter of the gas circulation hole 104d.SELECTED DRAWING: Figure 3
【課題】燃焼ガスの吐出能力を高くしつつ、生産性の向上や製造コストの低減を図る。【解決手段】エアバッグ装置のインフレータは、円筒状のハウジング内に設けられた内筒部材104と、内筒部材104内に充填された粒状のガス発生剤と、内筒部材104の内周面に外周が沿うコイルスプリング121と、を備え、内筒部材104の円筒壁に、発生したガスを吐出させるガス流通孔104dが形成されるとともに、コイルスプリング121のピッチが、ガス流通孔104dの直径よりも小さく設定されている。【選択図】図3
